Summary:
In the breeding programs breeders wish to compare the performance of inbred lines ind in particular which crosses would be the most profitable. Usually the comparison is based on continuous traits. In this case some genetical characteristics as general combining ability, specific combining ability, reciprocal effect and heterosis effect are very useful in the selection process. These characteristics are well defined in the continuous trait case. In the paper we propose some methods being analogue to that of continuous trait case. In particular, we propose the way of comparing the hybrids obtained by linexline crossing systemon the basis of the categorical trait distribution. Additionally, using simultaneous test procedure we can find lines having similar distribution. The theoretical considerations are illustrated with an example.
